often的位置、用法与搭配

often的位置、用法与搭配
 
一、often的位置
(1) 表示经常,通常放在行为动词之前,特殊动词(助动词、情态动词以及动词 be)之后。如:
He was often late for class. 他上课经常迟到。
We often go skating together. 我们常常一道去溜冰。
You must often come to see us. 你要常来看我们。
(2) 如果句子较短或为了强调,often可以放在句末。如:
You won’t see her often. 你不会常常看到她的。
如果句子较长或为了强调,often也可以放句首。如:
Often I miss breakfast and have an early lunch instead. 我常常不吃早餐,而吃一顿早午餐。
有时位于句首或句末是因为本身带有修饰语(如quite, very, so等)。如:
Quite often the phone rings when I’m in the bath. 电话经常在我洗澡时响。
When I was young, I used to play tennis very often. 我年轻时经常打网球。
(3) 有时often不是用于说明句子中的动词,而是用于说明整个句子的,此时也通用于句首。如:
Often, in the evening, we’d hear the sirens. 常常我们会在傍晚听到警报声。
Often, when he should have been doing something useful, he wasted his time drawing little pictures. 常常当他应当干些正经事时,他却浪费时间画小画。
(4) often置于句首时,有时其后可接倒装语序(但这并不是必需的)。如:
Often had she intended to speak of this. 她常想说及此事。
Often did we warn them not to do so. 我们曾多次警告过他们,不要这样做。
二、often时态
often通常与一般现在时或一般过去时连用,此外它还有以下用法值得注意:
(1) 与现在完成时连用,强调动词的一惯性和经常性。如:
You have often been told not to do that. 多次告诫过你别干那事。
I have often heard of him working hard. 我常听人说他刻苦用功。
(2) 与情态动词 will 连用,表示一种惯常的行为。如:
In fine weather, he will often sit in the sun for hours. 天气晴朗时,他常在阳光下坐好几个小时。
When you look at clouds they will often remind you of animals. 你观察云彩的时候,往往会联想起动物。
(3) 与情态动词 would 连用,表示过去惯常的行为。如:
When we were students we would often stay up all night. 我们当学生时,经常通宵不睡。
As he grew older, he would often talk about his war experiences. 他年岁大了,常常讲他的战争经历。
三、与否定词搭配
在否定句中,often可位于否定词not之前或之后。如:
They don’t often hold such parties. 他们不常开这样的晚会。
Statistics and surveys often don’t prove very much at all. 数据和调查常常证明不了什么。
四、用于习语as often as
用于习语 as often as,有两个意思是,一是表示……一样次数多。如:
He came as often as he could. 他尽可能常来。( www.52yufa.com)
二是起连词作用,相当于whenever,意为每当。如:
As often as I tried to ring him, the line was engaged. 每次我给他打电话都占线。
注意习语 as often as not(通常,常常),也可说成 more often than not。如:
When it’s foggy, the trains are late as often as not. 雾大时,火车往往晚点。
